PVC profile raw material automatic metering, mixing, conveying, storing and feeding process

Abstract

The invention belongs to the technical field of PVC production and machining, and particularly relates to a PVC profile raw material automatic metering, mixing, conveying, storing and feeding process.The process comprises a metering procedure, a mixing procedure and a conveying storage procedure; the metering procedure comprises multiple raw material bins, the discharging ends of the raw materialbins are connected with a spiral constant weight feeder, the spiral constant weight feeder is connected with a mixing tank in the mixing procedure through a first vertical lifting machine, the interior of the mixing tank is sequentially divided into a pre-stirring chamber, a heating stirring chamber and a cooling stirring chamber from top to bottom through a first partition board and a second partition board, a first stirring mechanism, a second stirring mechanism and a third stirring mechanism are arranged in the pre-stirring chamber, the heating stirring chamber and a cooling stirring chamber, in the conveying storage procedure, a spiral conveyor connected with an opening in the bottom face of the mixing tank is included, and the discharging end of the spiral conveyor is connected withthe storage tank through a second vertical lifting machine. The process has the beneficial effects that the PVC profile raw material production and machining efficiency is improved, and the productionand machining cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of PVC production and processing, and in particular relates to an automatic metering, mixing, conveying, storage and feeding process of PVC profile raw materials. Background technique [0002] In the PVC production process, PVC production raw materials need to go through various processes, such as metering, mixing, conveying, etc. Most of these processes are carried out in a single process and cannot be operated continuously, which greatly reduces production efficiency and increases the labor intensity of workers. In addition, the existing PVC metering, mixing, transportation and storage are all operated and processed in the form of a production line, so that the entire system will take up a lot of factory space and increase the cost of production, especially the PVC mixing process, which needs to involve pre-mixing, Multiple steps such as hot mixing and cold mixing, and the transportation of materials betwe...

Problems solved by technology

[0002] In the PVC production process, PVC production raw materials need to go through various processes, such as metering, mixing, conveying, etc. Most of these processes are carried out in a single process and cannot be operated continuously, which greatly reduces production efficiency and increases the labor intensity of workers.

In addition, the existing PVC metering, mixing, transportation and storage are all operated and processed in the form of a production line, so that the entire system will take up a lot of factory space and increase the cost of production, especially the PVC mixing process, which needs to involve pre-mixing, Multiple steps such as hot mixing and cold mixing, the transportation of materials between the mixing equipment used will consume a lot of manpower and material resources, which not only greatly limits the efficiency of PVC production and processing, but also increases the production cost
